Abstract

The invention concerns an electrochemical method and an electrochemical reactor wherein at least one electrochemical reaction chamber (5, 6) comprises a plurality of microchannels whereof the network of branches have a profile cross section at least partly curved with a radius of curvature greater than 30 µm and an area ranging between 2500µm2 and 20000µm2. The invention is applicable to synthesis of diastereoisomers by continuous regeneration of NADH or NADPH.
